Ekottaragama (Sanskrit fragments) 24.5.116

24.5.116

是時，世尊復作是念：「吾當於何處蹋浣此衣？」時，四天王知世尊心中所念，便舉大方石著水側，白世尊曰：「可在此而蹋衣。」

The Bhagavān again had the thought, “Where will I lay out the robe to wash it?”

The four god kings then knew that thought in the Bhagavān’s mind, so they presented a large, square stone to him, putting it next to the water. They said to the Bhagavān, “You can lay out your robes here.”
